To all whom it may concern:

Be it known that I, JOSEPH K. Been, a citizen of the United States, and residenz of Canandai a, in the county of Ontario State of ew York, have invented certain new and useful Improvements in Feeding Devices for Acetylene-Generators, of which the following is a specificati This invention relat o feeding devices for acetylene g1 nerators, and particularly to the pe in w ich the generator is separate cm the gas holder. i a

The invention consists in means for deliverin measured charges of calcium carbid to the body of water in the generator, and to other features that will be described.

Theobjectof the invention is to provide I a safe and accurately controllable feeding device for the carbid.

In the drawings Figure 1 is an elevation of a device embod mg this invention; Fig. 2 is a vertical section through the bottom of the hopper and through the feeding device, when the feeding device is receiving its charge of carbid from the hopper; Fig. 3 is a vertical section-on the same line as Fig. 2, showing the parts in the dischar ingposition; Fig. 4 is a perspective view o the slide of the feeding device; Fig. 5 is a perspective view of thefeeding device in its casing, parts bein broken away to exhibit construction; and ig. 6' is an elevation of an acetylene gas apparatus, embodying a modified form of the same invention.

The embodiment of this invention disclosed in the drawings accompanying this s ecification shows a gas holder 1 having a rising and falling bell 2 connected in a suitable manner with a separate generator 3, which is adapted to contain a body of water, into whlch calcium carbid is delivered for the production of the acetylene gas. It is important to deliver the carbid in definitely measured charges, with a frequency dependent upon the consumption of the ortant or the able of acetylene gas, and it is further im that the measurlng mechanism charges of the carbld shall not be ca npening a discharge passage from t e hopper or reservoir for cal-bid, to permit a continuous stream of carbid to flow out there from.

In the drawings, above the generator 3 is the casing 4 on top of which is placed the hopper or reservoir for contain ng a quantity of carbid suflicient to permit the continuous production of acetylene for any desired number of hours. The hopper preferably has itslower portion of an inverted confihaving at one end the pocket 7, which is open on to and has an inclined bottom. On the end of'the block is the gate 8, pivoted at 9 near the upper edge of the block, and having a suitable weight 10 at its lower edge to keep the gate closed. A lever or.trip finger 11 projects above thepivotal line of the gate. The wei ht 10 is heavy enough to keep the gate close when the charge of carbid is in the cup or pocket 7. The block 6 has a plane lower face, and slides upon a shelf 12 supported in any suitable manner inside the caslng 4, and preferably upon supports 13. The block 6 has also a flat or plane upper face, and cars 14 project from the rear end of said block for a purpose to be described.

Preferably the top 15 of the casing 4 is removable in order to give access to and permit removal of the slide and'its support the plate or body 12. To the top 15 is pivoted a scraper 16, whose lower ed e rests upon the top of the block 6, and is adapted to make close contact therewith at a point back of the reared e of the pocket 7, when the parts are in t e sition shown in Fig. 2. The inclination o the scraper 16 is such as to maintain this'close contact, and when the block, 6 is moved from one of its positions to the other, said scra er prevents the carbid from' flowing tower the back end of the block or slide 6.

An agitator is provided for moving the carbid in the bottom of the hopper 5, so as to prevent bridging and an improper flow thereof. In the present case, the agitator is a V-sha ed bar 17, with the apex of the V upwar and which is ivote at the extremity of one leg 18 to the ower edge of hopper 5, or to any other suitable part of the. apparatus. The other leg 19 is adapted to descend into the pocket 7, when the slide is reciprocated in the osition shown in Fig. 2, and thus -to tiltt e apex of the agitator, but when the slide is moved into the position shown in 3 the extremity of the free leg slides on the inclined bottom of the'apeit"? and then upon the top of the slidefi, as shown in Fi 3. Thus at each" reciprocation of the s 'de 6, the

agitator moves to stir the carbid in the bottom of the hopper.

The casing} is preferably rectangular, and the bed late 12 extends from one side thereofto the other, and the slide or block b also extends from one side theredf to the other. '1 he bed plate 12 is shorter than the length of the casing l, as shown in b'igs. 2 anu 6, so that the caubid may fallthrough and into the-body of the water underneath.

'10 a suitable part of the casing is fasened :1 lug 20, whicn is engaged by the trip finger 11 or the gate 8 when the slide reaches a discharging position, as shown in Fig. 3, and this opens the gate 8. 1n the present case, the tag 20' isffastened to the top 15 of the casing 4. q

Suitable means are provided for operating or reciprocating the slide or block 6. In

the present case, they consist of a shaft 21 PlVUlEd transversely in the casing and having one orinore arms 22, which pass upward through .hebed plate 12a'nd engage the sliding; block 6, so that as the shaft 21 is rocked, the slide or block (5 is rcciprocated. 1n the present case, the lugs 14 are perforated andthe arms 22 pass through the said perforations.

In order to operate the shaft 21 a crank 23 is provided outside the casing 1, which is connected in suitable manner to be rocked by the movement of the bell 2 of the gas holder, so that when the gas is exhausted to a suitable degree a new charge of carbid will be delivered in.o the water into the generator 3, and when the gas has accumulated in the bell to a desired degree, the carbid feedingapparatus is reset to take a new charge 'of carbid ready for delivery upon the movement of the bell above mentioned, after exhaustion of gas to the desired degree from the gas holder. In the present case, acrank 23 is connected by a link 24 to a' lever 25 pivoted between its ends at 26 to a suitable stationary support, such as the hopper 5, and at the end op )osite the connection of the link 24, the said ever is connected to. the hell 2.

In order to adjust and to vary the adjustment of the movement of the hell, with refer ence to the'discharge of carbid, I provide a variable connection between they-lever 25 and the hell 2, such as the link 27 having a series of perforations therethrough, pivoted at 28 at one end to the bell. A pin'or ivot 29 serves to connect the free end 0 the lever 25 with any one of the perforations of said series. According as t e lever 25 is connected with the llnk 27 nearer to its pivot 28,"so much the more quickly will the slide 6 discharge its carbid, because the shorter will be its stroke and the sooner will the exhaustion-of the bell operate said slide afte the delivery of the charge of carbid fromesaid slide;

In Fig. 6 is shown another operating de- Yice for the charge delivering apparatus. nstead of operating the crank 25 on the shaft 21 by a lever connected to the bell 2,

a water motor 30 may be employed havinga link connection 31 to said crank 23, whereby when a stream of water flows through the inlet pipe 32 to said water motor, the slide Owill be caused to reciprocate. In order to cause the motor to be operated when the supply of gas is exhausted from the bell to the desired degree, and also to shut off and stop the motor when the bell isfilled to the desired degree, the link 27 pivoted to the hell 2 at 28 is employed and said link is connected to an arm 33 adapted to open and close a valve 34 in the inlet connection to the molor. The valve is soset thatavhen the bell is exhausted 'to' the predetermined the valve willopen, and when the de ree, hell 2 is filled to the predetermined degree, the motor is stopped. i
